'IMPRO'VEMENT IN SKATES.

Specification forming part of Letters Patent N 0. 199,720, dated January29, 1878; application filed December 21, 1877.

.To all whom it may concern:

Be it known that I, GOTTFRIED KLOTZ, of

Bohmisch-Kamnitz, in the Empire of Austria, have invented a new andImproved Skate, of which the following is a specification:

In the accompanying drawings, Figure 1 represents a perspective view ofmy improved skate; Fig. 2,"a side view of the same in open position,ready to be attached to the foot; and Fig. 3 is a detail top view of thesole-plate, to show guide arrangement of sole-clamps.

Similar letters of reference indicate corresponding parts. i

This invention has reference to an improved skate that may be quicklyapplied to the heel and sole of the boot or shoe, after having been onceadjusted thereto, by the mere downward pressure of the foot on theraised sole-plate, so as to cause, by the leverage of the runner, thefirm fastening of the heeland sole clamps to the shoe; and the inventionconsists in the of parts, which described, and then set forth in theclaims.

Referring tothe drawings, A. represents the sole-plate, and B therunner, of my improved skate. The sole-plate A is provided with anotched heel-support, a, a longitudinalslot, b, in the heel part, andalateral guide-groove, d, in the middle part of the sole-plate.

The runner B is pivoted below the heel part to a recessed post or ears,0, at the under side of the sole-plate, so as to swing into openposition thereon, as shown in Fig. 2

The sole-plate A is secured by a forked part, f, below the ball portionof the sole-plate to a raised part, f, of the runner, and retainedrigidly thereon by a strong laterally-swinging lock-spring, G, thatpasses along the inclined upper surface of a lug, of part f and inlateral guide-recesses f of the part f, below the lug f. of thesole-p1ate A also binds on a front lug of the runner, so as to form,when the connection of sole'plate and runner is made, three points atwhich they are united.

By pressing the lock-spring sidewise the I sole-plate may be swung intoraised position on the pivot of the runner. The runner B The recessed orslotted toe end connects, by an upwardly-extending lug, g, with a shortslotted guide-piece, g, (indicatedin dotted lines in Fig. 2,) whichconnects with a long guide-plate, a clamp-screw, h, which may be screwedup by means of a key, these parts.

The long guide-plate D is provided at the wider front end with threeslots, central and inclined converging side slotof which the formerpasses along a guidescrew post, 6 while the latter engages pins '6 ofthe laterally-sliding sole-clamps F, which are guided in the lateralgroove 61 of the soleplate.

The leverage of the runner, on swinging down the sole-plate, actuatessimultaneously the heel and sole clamps, and fastens them to the shoe bythe mere downward pressure on the sole-plate. The heel andsole clampsmay be readily adjusted to any size of foot by loosening the clamp-screwh, and applying the sole-plate in raised position to the shoe, so thatthe heel and sole clamps may bereadily moved up against the heel andsole. The clamp-screw is then tightened, while the skate is held open,

and thereby the connection with the short runner-guide and long guideestablished.

When the skate is to be attached to the shoe, all that is required is toraise the sole plate, placethe foot thereon, and then press thesole-plate downward with the foot, so that the leverage of the runnerwill bind tightly the clamps on the heel and sole of the shoe, andcause, finally, the locking of sole-plate and runner by the lock-spring,and thereby the firm attachment of the skate to the shoe.

For detaching the skate, the lock-sprin g is pressed sidewise, the skateopened, and then removed from the foot by the simultaneous receding ofthe heel and sole clamps.

Having thus described my invention, I claim as new and desire to secureby Letters Patent- 1. In a skate, the combination of a slotted and.grooved sole-plate, having sliding and slotted guide-plates andclamp-screw, and adjustable heel and sole clamps, with the runner,pivoted to the heel part of the sole-plate, and

D, and with the heel-clamp E by so as to tightly-connect i-namely, a

engaging the slotted rear guide-piece by a projecting lug, to operatethe heel and sole clamps, substantially as set forth.

2. The combination, in a skate, of the soleplate A, havinglongitudinally and laterally recessed post f, and lock-spring O, withpivoted runner B, having raised part f, with lug f, substantially asspecified.

3. In a skate, the combination of the soleplate A, laterally-slidingsole-clamps I sliding and slotted guide-plate D, and connectingguide-piece g, and adjustable heel-clamp E, with clamp-screw h, toadjust the clamps to any size of foot, substantially as set forth.
